Filed April 12-. 1928 Patented Dec. 2, 1930 CLARENCE G. JOHNSON, OF HARTFORD CITY, INIHANA MOVABLE MOLDING FOB CLOSURE MEMBERS Application filed April 12,

The present invention pertains to a movable molding which is acted upon by a closure member such as a window for the purpose of sealing the lateral spaces between such member and the sides of its frame.

The principal object. of the invention is to provide a construction of this character which operates when the closure member is brought into closing position. The invention has been developed in this instance particularly for use in connection with windows of the sliding sash type wherein two w1ndows are mounted in a single frame. Movable moldings are provided at the sides of the frame parallel to the path of the sashes and adapted to engage opposite sides of the window. In other words, there is a pair of moldings for engagement with each sash.

The moldings are normally acted upon by spring mechanism whereby they are retracted from the sashes. The sashes moreover carry devices for engagingand shiftingthe moldings when coming to closed positlon, the relation being such that the moldings are drawn firmly into engagement with the sashes when the latter occupy their closed position. In this manner the lateral spaces between the sashes and the window frame are effectively sealed when the window is closed. The invention is fully disclosed by way of example in the following description and in the accompanying drawing, in which Figure 1 is an elevation of a window equipped with the invention;

Fig. 2 is a vertical section on the line 2-2 of Figure 1;

Fig. 3 is a detail horizontal section on the line 33 of Figure 1';

Fig.4 is a detail elevation of a modified 4 construction; and v Fig. 5 is a section on the line 5-5 of Figure 4.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figures 1, 2 and 3 is illustrated a window frame 1 in which are mounted two sliding sashes 2 and 3 in the usual manner. When the window is closed, one of the sashes 1928. Serial No. 269,477.

is disposed above the other as clearly shown in Figure 2.

A pair of moldings 4 are mounted at one side of the window and at the sides of the frame parallel to the path of the sashes.'65 These moldings are adapted to engage the lower sash 2 as will hereafter be more fully pointed out. In like manner another pair of moldings 5 are mounted at the other side of the window, sashes and adapted to engage the upper sash 3. 4

.The members 4 have oblique slots 6 inclined downwardly and toward the sash 2, and headed pins 7 fastened in the frame and passing through the slots, support these moldings for sliding movement. Similarly the moldings 5 have slots 8 inclined downwardl but away from the sash 3 and are slidabi y supported by headed pins 9 fixed in the window frame and passing through the slots. Springs 10 joining the upper ends ofthe moldings 4 to the top of the frame and similar springs 11 joining the lower ends of the moldings 5 to the window sill 12 normally cause the moldings to retract from the sashes 2 and 3.

Pins 13 and 14 extend from the moldings 4 and 5, substantially at the longitudinal mid points thereof, as shown more clearly in Figure 2. These pins are engageable respectively by a bracket 15 secured to the top of the sash 2 and by a bracket 16 secured to the base of the sash 3. It will now be apparent that the pins are engaged by their respective brackets-as the sashes approach closed position. The moldings 4 being in this manner moved downwardly a short distance are, by virtue ofthe inclined slots 6, drawn into firm engagement with the sash 2 by the time the 93 latter has reached its full closed position. In like manner the moldings 5 are drawn inwardly and upwardly to engage the sash 3 when the latter is in full closed position. These movements occur against the action of 95 the springs 10 and 11 which retract the moldings as the sashes are opened.

It will be apparent that the firm engagement of the moldings with the sashes closes the lateral spaces at the edges of the sashes 139 parallel to the path of the 60 window and at the sides and thereby prevents undesired drafts and circulation of air.

Figures 4 and 5 illustrate a modified device for normally retracting the moldings.- The molding is provided with an inserted spring cage or seat 21 having an inclined slot 22 for receiving the pin 23 anchored in the frame or jamb 24:. The seat is partly covered by a guard 25 secured to the pin 23, and between the seat and the guard is interposed a compressed spring 26. This spring, by bearing on the fixed guard and on the slidable seat normally causes the molding to move away from the sash 27 as shown in Figure 4.

Although specific embodiments of the invention have been illustrated and described it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

\Vhat I claim is 1. In a window frame, a window comprising a pair of slidable sashes, the combination of movable moldings at opposite sides of the window and at the sides of the frame parallel to the path of the sashes, said mold ngs being mounted to move towards and away from said sashes, pins carried by the moldings, and brackets carried by said sashes, said brackets being adapted to engage said pins and draw the moldings towards the sashes.

2. In a window frame, a window comprising a pair of slidable sashes, the combination of movable moldings at o posite sides of the f the frame parallel to the path of the sashes, said moldings being mounted to move towards and awa from said sashes, means carried by said sas es for drawing the adjacent moldings into engagement therewith. and means normally tending to draw said moldings away from said sashes.

3. In a window frame, a window comprising a pair of slidable sashes, the combination of movable moldings at opposite sides of the window and at the sides of the frame parallel to the path of the sashes, said moldings being mounted to move towards and away from said sashes, means carried by said sashes for drawing the adjacent moldings into engagement therewith, and spring means acting on said frame and moldings and adapted normally to hold said moldings spaced from the sashes.

4. In a frame having a closure member slidable therein, the combination of moldings disposed at the sides of the frame parallel to the path of said member and having oblique slots, pins fixed in said frame and passing through said slots to permit movement of said moldings towards and away from said closure member, and springs mounted in said slots and bearing on said pins to retract the moldings from said closure member.

5. In a frame having a closure member slidable therein, the combination of moldings disposed at the sides of the frame parallel to the path of said member and having oblique slots, pins fixed in said frame and passing through said slots to permit movement of .said moldin s towards and away from said
